John 14:3 And if I go and prepare a place for you, I will come back and take you to be with me that you also may be where I am.
Have you ever promised someone you would come back for them only to have things change in your life and you could not go back for them?
We all fall short of our promises because we live in an ever changing world and make promises not taking into account what could happen.
Jesus knew what would happen and still promised because He knew He could keep His promises to us.
Trust Him.
